Throughout my journey with Laravel, I’ve learned a lot of lessons that helped me improve the way I work and write code. Here are 10 key takeaways that made a real difference for me:
1. Start validation from the HTML, not just the backend
If you're using Blade, make sure to add required to your HTML fields. If a user submits an empty required field, it shouldn't even reach the server. Save your server from handling unnecessary requests.
2. Never trust the request without validation
Always validate incoming data. Avoid using request()->all(), especially if you're using guarded in your model—it could allow unexpected data to slip through.
3. Use resource or apiResource routes
This helps keep your routes organized and prevents your route files from becoming bloated and hard to manage.
4. Keep logic out of Laravel Resources
Don't put logic inside your Resource files. It can cause N+1 problems, especially when returning collections. It also makes your code easier for others to understand. Always use pagination for large datasets.
5. Use Eager Loading when you need relationships
Avoid N+1 problems by eager loading any relationships you know you'll use. Laravel 12 introduced automatic eager loading, but it's still good practice to manage it explicitly when needed.
6. Use logs to monitor your work
Laravel Logs and tools like Laravel Telescope are great for debugging and monitoring. Just make sure to secure Telescope if you’re using it in production.
7. Clean up old data
Regularly delete old logs and unused files. For example, when users update profile images, delete the old one. This helps you save disk space in the long run.
8. Always enforce Authorization
Use Guards, Policies, or Gates to protect your data. Never assume users should have access just because they’re logged in.
9. Enable Throttling / Rate Limiting
Don’t let a few users flood your system with requests. Throttling is your first line of defense against DDoS attacks.
10. Caching is not a luxury
Use cache for data that’s accessed frequently and doesn’t change often. It makes a big difference in performance.
Final Thought:
You're building for all kinds of users، always be prepared for the worst-case scenario.
